PROBLEM TO BE SOLVED: To release a metal compound into a metal element form as a metal element form by electromagnetic wave irradiation even when the film is thin and excellent in electromagnetic wave absorption ability, and to perform a metal deposition step in post-processing well. A polyester film that can be used is provided. [Solution] A monolayer or multilayer polyester film having a total thickness of 5 to 500 μm and stretched at least uniaxially made of thermoplastic polyester, the polyester film comprising a metal compound activated by electromagnetic wave irradiation in an amount of 0.5 to 15 Containing 0.1 to 15% by weight of an electromagnetic wave absorbing material.
